The storage devices may not embody signals. In acertain embodiment, the storage devices only employ signals foraccessing code.

Certain of the functional units described in this specification may belabeled as modules, in order to more particularly emphasize theirimplementation independence. For example, a module may be implemented asa hardware circuit comprising custom very-large-scale integration(“VLSI”) circuits or gate arrays, off-the-shelf semiconductors such aslogic chips, transistors, or other discrete components. A module mayalso be implemented in programmable hardware devices such as fieldprogrammable gate arrays, programmable array logic, programmable logicdevices or the like.

Modules may also be implemented in code and/or software for execution byvarious types of processors. An identified module of code may, forinstance, include one or more physical or logical blocks of executablecode which may, for instance, be organized as an object, procedure, orfunction. Nevertheless, the executables of an identified module need notbe physically located together, but may include disparate instructionsstored in different locations which, when joined logically together,include the module and achieve the stated purpose for the module.

Indeed, a module of code may be a single instruction, or manyinstructions, and may even be distributed over several different codesegments, among different programs, and across several memory devices.Similarly, operational data may be identified and illustrated hereinwithin modules, and may be embodied in any suitable form and organizedwithin any suitable type of data structure. The operational data may becollected as a single data set, or may be distributed over differentlocations including over different computer readable storage devices.Where a module or portions of a module are implemented in software, thesoftware portions are stored on one or more computer readable storagedevices.

Any combination of one or more computer readable medium may be utilized.The computer readable medium may be a computer readable storage medium.The computer readable storage medium may be a storage device storing thecode. The storage device may be, for example, but not limited to, anelectronic, magnetic, optical, electromagnetic, infrared, holographic,micromechanical, or semiconductor system, apparatus, or device, or anysuitable combination of the foregoing.

More specific examples (a non-exhaustive list) of the storage devicewould include the following: an electrical connection having one or morewires, a portable computer diskette, a hard disk, a random access memory(“RAM”), a read-only memory (“ROM”), an erasable programmable read-onlymemory (“EPROM” or Flash memory), a portable compact disc read-onlymemory (“CD-ROM”), an optical storage device, a magnetic storage device,or any suitable combination of the foregoing. In the context of thisdocument, a computer readable storage medium may be any tangible mediumthat can contain, or store a program for use by or in connection with aninstruction execution system, apparatus, or device.

Code for carrying out operations for embodiments may be any number oflines and may be written in any combination of one or more programminglanguages including an object oriented programming language such asPython, Ruby, Java, Smalltalk, C++, or the like, and conventionalprocedural programming languages, such as the “C” programming language,or the like, and/or machine languages such as assembly languages. Thecode may execute entirely on the user's computer, partly on the user'scomputer, as a stand-alone software package, partly on the user'scomputer and partly on a remote computer or entirely on the remotecomputer or server. In the latter scenario, the remote computer may beconnected to the user's computer through any type of network, includinga local area network (“LAN”) or a wide area network (“WAN”), or theconnection may be made to an external computer (for example, through theInternet using an Internet Service Provider).

FIG. 3 depicts one embodiment of an apparatus 300 that may be used fortransmission power control. The apparatus 300 includes one embodiment ofthe network unit 104. Furthermore, the network unit 104 may include aprocessor 302, a memory 304, an input device 306, a display 308, atransmitter 310, and a receiver 312. As may be appreciated, theprocessor 302, the memory 304, the input device 306, the display 308,the transmitter 310, and the receiver 312 may be substantially similarto the processor 202, the memory 204, the input device 206, the display208, the transmitter 210, and the receiver 212 of the remote unit 102,respectively.

In certain embodiments, the transmitter 310: transmits first schedulinginformation for a first uplink transmission on a first serving cell at afirst time instant, wherein the first scheduling information comprises afirst transmission period and a first numerology; and transmits secondscheduling information for a second uplink transmission on a secondserving cell at a second time instant.

In certain embodiments, thereceiver 312: receives a first portion of the first uplink transmissionwith a first transmission power during a first time period in which thefirst transmission period does not overlap with the second transmissionperiod, wherein the first transmission power is based at least partly onthe first scheduling information, and a first total transmission powerduring the first time period equals the first transmission power; andreceives a second portion of the first uplink transmission during asecond time period in which the first transmission period overlaps withthe second transmission period. In such embodiments: a second totaltransmission power during the second time period is greater than orequal to the first total transmission power; and, in response to thesecond total transmission power being equal to the first totaltransmission power, the second portion of the first uplink transmissionis received with a transmission power less than the first transmissionpower.

As used herein, in some embodiments, a TX beam and RX beamcorrespondence configured at a TRP and a UE may be as follows: a TX beamand RX beam correspondence at a TRP may be maintained if at least one ofthe following is satisfied: 1) the TRP is able to determine a TRP RXbeam for uplink reception based on a UE's downlink measurement on theTRP's one or more TX beams; and 2) the TRP is able to determine a TRP TXbeam for downlink transmission based on the TRP's uplink measurement onthe TRP's one or more RX beams; and a TX beam and RX beam correspondenceat a UE may be maintained if at least one of the following issatisfied: 1) the UE is able to determine a UE TX beam for an uplinktransmission based on the UE's downlink measurement on the UE's one ormore RX beams; and the UE is able to determine a UE RX beam for downlinkreception based on the TRP's indication based on an uplink measurementon the UE's one or more TX beams.

Moreover, as used herein, an antenna port may be defined such that achannel over which a symbol on the antenna port is conveyed may beinferred from a channel over which another symbol on the same antennaport is conveyed.

Furthermore, as used herein, two antenna ports may be considered QCL iflarge-scale properties of a channel over which a symbol on one antennaport is conveyed may be inferred from the channel over which a symbol onthe other antenna port is conveyed. The large-scale properties mayinclude one or more of: delay spread, doppler spread, doppler shift,average gain, average delay, and spatial RX parameters. In addition, twoantenna ports may be QCL with respect to a subset of the large-scaleproperties. Moreover, spatial RX parameters may include one or more of:AoA, dominant AoA, average AoA, angular spread, PAS of AoA, average AoD,PAS of AoD, transmit and/or receive channel correlation, transmit and/orreceive beamforming, spatial channel correlation, and so forth.

As used herein, an antenna port may be a logical port that maycorrespond to a beam (resulting from beamforming) or may correspond to aphysical antenna on a device. In some embodiments, a physical antennamay be mapped directly to a single antenna port. In such embodiments, anantenna port corresponds to an actual physical antenna. In certainembodiments, a set of physical antennas, a subset of physical antennas,an antenna set, an antenna array, or an antenna sub-array may be mappedto one or more antenna ports after applying complex weighting, a cyclicdelay, or both to a signal on each physical antenna. In someembodiments, a physical antenna set may have antennas from a singlemodule, a single panel, multiple modules, or multiple panels. Theweights may be fixed as in an antenna virtualization scheme, such asCDD. In some embodiments, a procedure used to determine antenna portscorresponding to physical antennas may be specific to a deviceimplementation and may be transparent to other devices.

In some embodiments, DL TX antenna ports may correspond to antenna portsof a single CSI-RS resource, or antenna ports of different CSI-RSresources (e.g., a first subset including at least one DL TX antennaport corresponding to a first CSI-RS resource, and a second subsetincluding at least one DL TX antenna port corresponding to a secondCSI-RS resource).

In certain embodiments, a DL TX antenna port may be associated with oneor more SS blocks. In such embodiments, each SS block may have acorresponding SS block index (e.g., a number or value that indicates anSS block). In various embodiments, an antenna port associated with afirst SS block (e.g., having a first SS block index) may correspond to afirst DL TX beam (e.g., beamforming pattern), and an antenna portassociated with a second SS block (e.g., having a second SS block index)may correspond to a second DL TX beam. In such embodiments, depending onthe SS block, an antenna port may correspond to different DL TX beams(e.g., the first DL TX beam or the second DL TX beam). As may beappreciated, the first DL TX beam may be different from the second DL TXbeam. Furthermore, the first SS block may be different from the secondSS block resulting in the first SS block index being different from thesecond SS block index. In some embodiments, a first SS block may betransmitted at a first time instance and a second SS block may betransmitted at a second time instance. In other embodiments, first andsecond SS block transmission instances may overlap either completely orat least partially. In one embodiment, a UE may assume that anytransmission instance of an SS block with the same SS block index istransmitted on the same antenna port. In certain embodiments, a UE maynot assume that a channel over which a first SS block with a first SSblock index is conveyed may be inferred from a channel over a second SSblock with a second SS block index (e.g., the second SS block index isdifferent from the first SS block index) is conveyed even if the firstand second SS blocks are transmitted on the same antenna port.

In various embodiments, a DL TX antenna port may be associated with oneor more CSI-RS resources. In some embodiments, an antenna portassociated with a first CSI-RS resource (e.g., having a first CSI-RSresource index) may correspond to a first DL TX beam (e.g., beamformingpattern), and an antenna port associated with a second CSI-RS resource(e.g., having a second CSI-RS resource index) may correspond to a secondDL TX beam. In such embodiments, depending on the CSI-RS resource, anantenna port may correspond to different DL TX beams (e.g., the first DLTX beam or the second DL TX beam. As may be appreciated, the first DL TXbeam may be different from the second DL TX beam. Furthermore, the firstCSI-RS resource may be different from the second CSI-RS resourceresulting in the first CSI-RS resource index being different from thesecond CSI-RS resource index. In some embodiments, the first CSI-RSresource may be transmitted at a first time instance and the secondCSI-RS resource may be transmitted at a second time instance. In otherembodiments, first and second CSI-RS resource transmission instances mayoverlap either completely or at least partially. In one embodiment, a UEmay assume that any transmission instance of a CSI-RS resource with thesame CSI-RS resource index is transmitted on the same antenna port. Incertain embodiments, a UE may not assume that a channel over which afirst CSI-RS resource with a first CSI-RS resource index is conveyed maybe inferred from a channel over a second CSI-RS resource with a secondCSI-RS resource index (e.g., the second CSI-RS resource index isdifferent from the first CSI-RS resource index) is conveyed even if thefirst and second CSI-RS resources are transmitted on the same antennaport.

In various configurations, such as 5G NR RAT that supports both singlecarrier and multiple carrier operations, a UE may communicate with oneor more serving cells to enhance coverage, facilitate efficient use of aspectrum, support various network deployments, access differentservices, and/or access different traffic types. In such configurations,CA may provide a framework for the UE to operate with multiple CCs in acoherent fashion. In certain configurations, there may be threedifferent modes of operation for CA that include: intra-band contiguousCA, intra-band non-contiguous CA, and inter-band CA. In someembodiments, such as for intra-band contiguous CA and/or intra-bandnon-contiguous CA, a UE may have a single PA for operating on one ormore CCs. In various embodiments, such as for inter-band CA and/orintra-band non-contiguous CA, a UE may have different PAs for operatingon one or more CCs.

In some configurations, such as in an LTE-CA framework, there may be oneor more of fixed slots, subframe sizes, fixed numerologies, SCSs, and/orfixed grant-to-transmission timing offsets for different serving cells.In various configurations, such as for intra-band contiguous CA, a UEmay handle a delay spread of up to 0.26 us among different componentcarriers (e.g., monitored at a receiver), and for intra-bandnon-contiguous CA and inter-band CA, a UE may handle a delay spread ofup to 30.26 us among different component carriers (e.g., monitored atthe receiver). Such a delay spread of up to 30.26 us may be at most halfan LTE-symbol.

In various configurations, such as in a 5G-NR CA framework, a slot sizemay vary (e.g., the slot size may have between 2 and 14 symbols), anumerology and/or an SCS may be different, and/or agrant-to-transmission timing offset may be different for differentserving cells. In some configurations, multiple services may be offeredwith different performance requirements and/or priorities. Therefore, insome embodiments, a UE operating with NR-CA may use multipleheterogeneous UL transmissions for different serving cells. Theseheterogeneous UL transmissions may be categorized into the followingcategories: (i) slot-level synchronous and/or symbol-level synchronous,and/or (ii) slot-level asynchronous and/or symbol-level asynchronous. Asmay be appreciated, starting times of different UL transmissions fordifferent serving cells may be different. According, variousheterogeneous overlapping UL transmissions may be categorized asslot-level asynchronous and/or symbol-level asynchronous. Thus, a UE(e.g., in a 5G-NR CA framework) may be designed to handle a transmissiontiming offset of up to 500 us between the two CGs.

In various embodiments, a missing element in various solutions forheterogeneous UL transmissions (e.g., in a 5G-NR CA framework) may bethat an abrupt phase change in the PA, that may be caused by suddenlychanging from a certain total power level for one set of transmissionsto a certain different total power level for another set oftransmissions, may not be addressed. Such an abrupt phase changeinvalidates the previous channel estimation and prevents the coherentdemodulation facilitated by a previous DMRS to be applicable for thesecond set of transmissions. Note that, not puncturing the DMRS orkeeping a constant power for DMRS cannot resolve this issue. Asdescribed herein, a fixed total power for a power amplifier may be keptin order to avoid phase discontinuity, or “additional” DMRS may beinserted in the transmissions, e.g., immediately at the beginning of thesecond set of transmissions (and in general, immediately following anyabrupt power change to the PA), if there is an abrupt power changeand/or phase change/discontinuity.

In some embodiments, to facilitate diverse heterogeneous ULtransmissions that overlap in time and each have certain SINRrequirements, appropriate power allocation for UE transmissions may beimportant. In certain embodiments, a UE may ensure that, regardless ofan operating mode and diverse heterogeneous UL transmissions, maximumtransmission power levels per serving cell and a total power level forall serving cells set by a network are adhered to.

Various methods described herein present, for a UE in a wireless network(e.g., 5G NR) operated with multiple CCs in a CA fashion, powerallocation methods for overlapping UL transmissions with differentdurations, required power levels, and/or priorities for a UE withsingle/multiple PA(s), along with qualitative criteria for thenetwork/UE to select an appropriate method based on the properties ofdifferent transmissions. In various methods, a key focus may be to makesure appropriate channel estimation and coherent decoding is alwaysguaranteed irrespective of the varying transmission powers and theresulting phase discontinuity.

Various methods described herein relate to configurations in which a UEperforms one or more heterogeneous UL transmissions at the same time(e.g., multiplexing of slot based PUSCH, non-slot based PUSCH, longPUCCH, short PUCCH, the same SCS among UL transmissions, and/ordifferent SCS among UL transmissions). The one or more heterogeneous ULtransmissions either at least partially overlap in time or fully overlapin time, and each UL transmission of the one or more heterogeneous ULtransmissions may have a different duration, a different requiredtransmit power, and/or a different priority. The one or moreheterogeneous UL transmissions may occur within one serving cell and/oracross different serving cells of different carrier frequencies. Thedifferent carrier frequencies may be in the same frequency band ordifferent frequency bands. In one embodiment, if one or moreheterogeneous transmissions occur within one cell or across differentcells of intra-band contiguous CA and/or co-located cells, symbol timingof one UL transmission of a longer symbol duration may be aligned withsymbol timing of another UL transmission of a shorter symbol duration(e.g., if the serving cells are in the same TAG). In another embodiment,if one or more heterogeneous transmissions occur across different cellsof intra-band non-contiguous CA and/or non-co-located cells, symboltiming of one UL transmission of a longer symbol duration may not bealigned with symbol timing of another UL transmission of a shortersymbol duration (e.g., if the serving cells are in different TAG). Insome embodiments, a UE may use one PA for multiple transmissions withinone cell or across aggregated carriers for intra-band contiguous CAand/or intra-band non-contiguous CA, while the UE may use separate PAsfor inter-band CA and/or intra-band non-contiguous CA.

FIG. 4 is a schematic block diagram illustrating one embodiment of asystem 400 including overlapping transmissions. The system 400 includesa first UL transmission 402 (“UL1”) that occurs over a firsttransmission period 404 (“T1”), and a second UL transmission 406 (“UL2”)that occurs over a second transmission period 408 (“T2”). The firsttransmission period 404 may have a greater duration than the secondtransmission period 408. Moreover, the first transmission period 404 atleast partially overlaps or completely overlaps in time with the secondtransmission period 408.

In some embodiments, a CA-capable UE may be scheduled (e.g., either bygrant-based scheduling or grant-free based scheduling) for the first ULtransmission 402 and for the second UL transmission 406 (e.g., thesecond UL transmission 406 may be scheduled after the first ULtransmission 402). The first UL transmission 402 may have a firstnumerology and/or SCS (“μ1”), and a first transmit power (“P1”) on afirst serving cell (“c1”) on a first component carrier (“CC1”). Invarious embodiments, the first UL transmission 402 may be for eMBBand/or slot-based PUSCH. The second UL transmission 406 may have asecond numerology and/or SCS (“μ2”), and second transmit power (“P2”) ona second serving cell (“c2”) on a second component carrier (“CC2”). Insome embodiments, the second UL transmission 406 may be for URLLC and/orPUCCH. In certain embodiments, the second UL transmission 406 may have ahigher priority than the first UL transmission 402. In variousembodiments, slot-timing and/or symbol-timing of c1 and c2 areasynchronous for a UE. Accordingly, a UE receiver detects different DLslot-boundaries and/or symbol-boundaries for c1 and c2 even if theserving cells have a common numerology and/or SCS. Various methods aredescribed in relation to FIGS. 5 through 9 for a UE to perform twoheterogeneous UL transmissions using one PA.

FIG. 5 is a schematic block diagram illustrating one embodiment of atiming diagram 500 of power settings. The timing diagram 500 illustratesa first transmission power 502 for the first UL transmission 402described in FIG. 4, a second transmission power 504 for the second ULtransmission 406 described in FIG. 4, and a total transmission power 506that is a sum of the first transmission power 502 and the secondtransmission power 504. Furthermore, the timing diagram 500 illustratesa first time 508, a second time 510, a third time 512, and a fourth time514. The first time 508 corresponds to a starting time of the first ULtransmission 402, and the fourth time 514 corresponds to an ending timeof the first UL transmission 402, thus, the first transmission period404 of FIG. 4 equals the time between the first time 508 and the fourthtime 514. Moreover, the second time 510 corresponds to a starting timeof the second UL transmission 406, and the third time 512 corresponds toan ending time of the second UL transmission 406, thus, the secondtransmission period 408 of FIG. 4 equals the time between the secondtime 510 and the third time 512.

In the embodiment illustrated in FIG. 5, a UE attempts to keep the totaltransmission power 506 constant during the first transmission period 404which encompasses the second transmission period 408. In one embodiment,the first UL transmission 402 is scheduled prior to the second ULtransmission 406, and the UE determines the power settings based on afirst power requirement P1 for the first UL transmission 402 and doesnot take into account the power requirement P2 for the second ULtransmission 406.

As illustrated, the UE may transmit, with power P1, the first N1 symbols(e.g., having a duration less than the first transmission period 404) ofthe first UL transmission 402 prior to and up to the start of the secondUL transmission 406. Thus, between the first time 508 and the secondtime 510, the first transmission power 502 equals P1. In someembodiments, the duration between the first time 508 and the second time510 may be in units corresponding to a symbol duration of the first ULtransmission 402 symbol duration. The symbol duration may be based onthe first numerology and/or subcarrier-spacing μ1. In certainembodiments, a UE implementation may determine if and what waveform theUE transmits between the end of the last symbol (e.g., symbol boundary)of the N1 symbols of the first UL transmission 402 just prior to thestart of the second UL transmission 406 and the start of the firstsymbol of the second UL transmission 406 to facilitate proper decodingusing a first DMRS (“DMRS1”) within the first N1 symbols. In oneembodiment, the first DMRS is transmitted at or near the beginning ofthe first UL transmission 402 (e.g., front-loaded near the beginning ofthe first N1 symbols).

During the second transmission period 408, the UE may transmit thesecond UL transmission 406 with a power {tilde over (P)}₂=min{P2, P1}.Thus, between the second time 510 and the third time 512, the secondtransmission power 504 equals a minimum of P1 and P2. Because the secondtransmission period 408 starts at the second time 510 and ends at thethird time 512, the second transmission power 504 equals zero betweenthe first time 508 and the second time 510, and between the third time512 and the fourth time 514.

During the first transmission period 404 between the second time 510 andthe third time 512, the first transmission power 502 equals a maximum of0 and P1 minus P2 (e.g., Max{0, P1−P2}) or equivalently a maximum of 0and P1 minus {tilde over (P)}₂ (e.g., Max{0, P1−{tilde over (P)}₂).Accordingly, if P1≤P2 (or P1≤{tilde over (P)}₂), the UE may cease thetransmission of the first UL transmission 402 for the duration of T2(e.g., the portion and/or duration of the overlapped transmissionbetween UL1 and UL2, some fraction of a UL1 symbol duration may also beincluded as overlapped transmission time immediately prior to and/orafter the UL2 transmission to account for any symbol boundarymisalignment between UL1 and UL2), and resume the first UL transmission402 (with the same symbol-timing as that for the transmitted first N1symbols of UL1) of second N2 symbols with power P1 upon completion ofthe second UL transmission 406. In other words, during the firsttransmission period 404 between the third time 512 and the fourth time514, the first transmission power 502 equals P1. Accordingly, the totaltransmission power 506 of the PA is fixed at P1 (e.g., constantly heldat P1) for the duration of the first transmission period 404. Thus, forthe duration of the first transmission period 404, there may be no phasediscontinuity between the first N1 symbols transmission of the first ULtransmission 402 and the second N2 symbols transmission of the first ULtransmission 402 (e.g., the symbols following the duration T2). In oneembodiment, some subcarriers (e.g., RE) of an OFDM and/or DFTS-OFDMsymbol of the first UL transmission 402 may be reserved in advance(e.g., the UE performs rate-matching around those reserved subcarriers),and the UE may use those reserved subcarriers to send an indication to anetwork entity (e.g., gNB) to indicate whether puncturing of the firstUL transmission 402 due to a power limitation is performed (e.g., bysending an indication to cell c1 with a flag “F1” set to zero to denotepuncturing, in one example F1 (e.g., having one or more bits) mayrepresent a power offset term corresponding to any change in UL1transmit power during the overlap duration T2 with one of the states ofF1 representing puncturing).

Moreover, if P1>P2 (or P1>{tilde over (P)}₂), the UE may adjust and/orscale the first UL transmission 402 to result in the first transmissionpower 502 equal to {tilde over (P)}₁(=P1−P2) during T2. Upon completionof the second UL transmission 406, the UE may re-adjust and/or re-scalethe first UL transmission 402 back to the first transmission power 502being equal to P1 for the second N2 symbols of the first UL transmission402. In one embodiment, the UE may transmit an indication to cell c1with the flag F1=1 denoting no puncturing. As may be appreciated, thefront-loaded demodulation reference signal DMRS1 may facilitate coherentdecoding of UL1 because the PA power setting is unchanged over theduration T1.

FIG. 6 is a schematic block diagram illustrating another embodiment of atiming diagram 600 of power settings. The timing diagram 600 illustratesa first transmission power 602 for the first UL transmission 402described in FIG. 4, a second transmission power 604 for the second ULtransmission 406 described in FIG. 4, and a total transmission power 606that is a sum of the first transmission power 602 and the secondtransmission power 604. Furthermore, the timing diagram 600 illustratesa first time 608, a second time 610, a third time 612, and a fourth time614. The first time 608 corresponds to a starting time of the first ULtransmission 402, and the fourth time 614 corresponds to an ending timeof the first UL transmission 402, thus, the first transmission period404 of FIG. 4 equals the time between the first time 608 and the fourthtime 614. Moreover, the second time 610 corresponds to a starting timeof the second UL transmission 406, and the third time 612 corresponds toan ending time of the second UL transmission 406, thus, the secondtransmission period 408 of FIG. 4 equals the time between the secondtime 610 and the third time 612.

In the embodiment illustrated in FIG. 6, a UE does not aim for aconstant total transmission power 606 over the first transmission period404 which encompasses the second transmission period 408, but may assigna higher power level to the second UL transmission 406 than in theembodiment illustrated in FIG. 5. Moreover, the embodiment illustratedin FIG. 6 attempts to avoid puncturing of the first UL transmission 402thereby requiring insertion of additional DMRS as the total transmissionpower 606 changes.

As illustrated, the UE may transmit, with power P1, the first N1 symbols(e.g., having a duration less than the first transmission period 404) ofthe first UL transmission 402 prior to and up to the start of the secondUL transmission 406. Thus, between the first time 608 and the secondtime 610, the first transmission power 602 equals P1. In one embodiment,a first DMRS is transmitted at or near the beginning of the first ULtransmission 402 (e.g., front-loaded near the beginning of the first N1symbols).

During the second transmission period 408, the UE may transmit thesecond UL transmission 406 with the power P2. Thus, between the secondtime 610 and the third time 612, the second transmission power 604equals P2. Because the second transmission period 408 starts at thesecond time 610 and ends at the third time 612, the second transmissionpower 604 equals zero between the first time 608 and the second time610, and between the third time 612 and the fourth time 614.

During the first transmission period 404 between the second time 610 andthe third time 612, the first transmission power 602 equals Min{Max{0,P_(CMAX,c1)−P2}, P1}. Moreover, during the first transmission period 404between the third time 612 and the fourth time 614, the firsttransmission power 602 equals Min{Max{P2, P_(CMAX,c1)}, P1+P2}.Accordingly, if P2≥P_(CMAX,c1), where P_(CMAX,c1) is the maximumconfigured output power for serving cell c1, the UE may cease thetransmission of the first UL transmission 402 for the duration of T2,and resume the first UL transmission 402 with the first transmissionpower 602 equal to {tilde over (P)}₁ (=P_(CMAX,c1)) upon completion ofthe second UL transmission 406. In one embodiment, the UE may send anindication to cell c1 (e.g., a flag F2=0) to indicate puncturing.Because the UE output power setting is changed from P1 to {tilde over(P)}₁ (=P_(CMAX,c1)) during the first UL transmission 402, the UE maymultiplex an additional demodulation reference signal (“DMRS2”) into thefirst UL transmission 402 to facilitate coherent decoding after changingthe total power transmission 606 at the third time 612. As may beappreciated, with a change of the PA power setting, a phase of an outputsignal may abruptly change resulting in a phase discontinuity and,accordingly, a new DMRS may be used to enable a gNB receiver to updateits phase estimation. For example, a UE may not transmit (e.g.,puncture) scheduled data on some or all subcarriers of an OFDM and/orDFTS-OFDM symbol of the first UL transmission 402 immediately followingthe second UL transmission 406 and may transmit DMRS2 on thosesubcarriers. As may be appreciated, if {tilde over (P)}₁>P1, powerboosting for the remaining transmission time of the first ULtransmission 402 after the third time 612 may compensate for a potentialperformance loss occurring due to power reduction (e.g., puncturing)occurring during the overlap duration T2.

Moreover, if P2<P_(CMAX,c1) and P_(CMAX,c1)−P2<P1, the UE may adjust thefirst UL transmission 402 to result in the first transmission power 602equal to {tilde over (P)}₁(=P_(CMAX,c1)−P2) during T2. Upon completionof the second UL transmission 406, the UE may re-adjust the first ULtransmission 402 to result in the first transmission power 602 equal toP_(CMAX,c1) and complete the first UL transmission 402. In someembodiments, the UE may send an indication to cell c1 to indicatepuncturing (e.g., a flag F2=1) that may occur if additional signals aretransmitted, such as additional DMRS. Because the UE output powersetting is changed from P1 to P_(CMAX,c1) during the first ULtransmission 402, the UE may multiplex the additional demodulationreference signal DMRS2 into the first UL transmission 402 to facilitatecoherent decoding after changing the total power transmission 606 at thesecond time 610.

Furthermore, if P2<P_(CMAX,c1) and P_(CMAX,c1)−P2≥P1, the UE maycontinue transmitting the first UL transmission 602 with the firsttransmission power 602 equal to P1 during T2. Upon completion of thesecond UL transmission 406, the UE may re-adjust the first ULtransmission 402 to result in the first transmission power 602 equal toP1+P2 and complete the first UL transmission 402. (the UE may send anindication to cell c1, e.g., a flag F2=1). In some embodiments, the UEmay send an indication to cell c1 to indicate puncturing (e.g., a flagF2=1). Because the UE output power setting is changed from P1 to P1+P2during the first UL transmission 402, the UE may multiplex theadditional demodulation reference signal DMRS2 into the first ULtransmission 402 to facilitate coherent decoding after changing thetotal power transmission 606 at the second time 610. The total powertransmission 606 is equal to P1 between the first time 608 and thesecond time 610, and the total power transmission 606 is equal toMin{P_(CMAX,c1), P1+P2} between the second time 610 and the fourth time614.

FIG. 7 is a schematic block diagram illustrating a further embodiment ofa timing diagram 700 of power settings. The timing diagram 700illustrates a first transmission power 702 for the first UL transmission402 described in FIG. 4, a second transmission power 704 for the secondUL transmission 406 described in FIG. 4, and a total transmission power706 that is a sum of the first transmission power 702 and the secondtransmission power 704. Furthermore, the timing diagram 700 illustratesa first time 708, a second time 710, a third time 712, and a fourth time714. The first time 708 corresponds to a starting time of the first ULtransmission 402, and the fourth time 714 corresponds to an ending timeof the first UL transmission 402, thus, the first transmission period404 of FIG. 4 equals the time between the first time 708 and the fourthtime 714. Moreover, the second time 710 corresponds to a starting timeof the second UL transmission 406, and the third time 712 corresponds toan ending time of the second UL transmission 406, thus, the secondtransmission period 408 of FIG. 4 equals the time between the secondtime 710 and the third time 712.

In the embodiment illustrated in FIG. 7, a UE does not aim for aconstant total transmission power 706 over the first transmission period404 which encompasses the second transmission period 408, but unlike theembodiment illustrated in FIG. 6, the UE attempts to assign a maximumavailable power level to each UL transmission thereby reducing a chanceof repetitive puncturing of one or more symbols of the first ULtransmission 402, but requiring additional DMRS each time the totaltransmission power 706 changes.

As illustrated, the UE may transmit, with power P1, the first N1 symbols(e.g., having a duration less than the first transmission period 404) ofthe first UL transmission 402 prior to and up to the start of the secondUL transmission 406. Thus, between the first time 708 and the secondtime 710, the first transmission power 702 equals P1. In one embodiment,a first DMRS is transmitted at or near the beginning of the first ULtransmission 402 (e.g., front-loaded near the beginning of the first N1symbols).

During the second transmission period 408, the UE may transmit thesecond UL transmission 406 with the power P2. Thus, between the secondtime 710 and the third time 712, the second transmission power 704equals P2. Because the second transmission period 408 starts at thesecond time 710 and ends at the third time 712, the second transmissionpower 704 equals zero between the first time 708 and the second time710, and between the third time 712 and the fourth time 714.

During the first transmission period 404 between the second time 710 andthe third time 712, the first transmission power 702 equalsMin{P_(CMAX,c1), P_(CMAX,total)−P2, (1+γ)P1}. Moreover, during the firsttransmission period 404 between the third time 712 and the fourth time714, the first transmission power 702 equals Min{P_(CMAX,c1), (1+γ)P1}.Accordingly, if P2=P_(CMAX,total), where P_(CMAX,total) is the maximumconfigured total and/or aggregate output power across all cells (e.g.,CC1 and CC2 in this example) for carrier aggregation or dualconnectivity (e.g., in the notation of 3GPP LTE and/or NRspecifications, P_(CMAX)(i1) for CA in subframe and/or slot index i, orP_(CMAX)(i1,i2) for DC in subframe and/or slot pair indices i1 and i2),the UE may cease the transmission of the first UL transmission 402 forthe duration of T2, and resume the first UL transmission 402 with thefirst transmission power 702 equal to {tilde over (P)}₁ (=P_(CMAX,c1))upon completion of the second UL transmission 406. In one embodiment,the UE may send an indication to cell c1 (e.g., a flag F3=0) to indicatepuncturing. Because the UE total output power setting is changed from P1to P2 (=P_(CMAX,total)) and then to {tilde over (P)}₁ (=P_(CMAX,c1))during the first UL transmission 402, and the UE stops the first ULtransmission 402 during T2, the UE may multiplex an additionaldemodulation reference signal DMRS2 into the first UL transmission 402(e.g., during the duration in which the first transmission power 702 isequal to {tilde over (P)}₁) to facilitate coherent after upon changingthe total power transmission 706 at the third time 712. For example, aUE may not transmit (e.g., puncture) scheduled data on some or all ofthe subcarriers of the OFDM and/or DFTS-OFDM symbol of the first ULtransmission 402 immediately following the completion of the second ULtransmission 406 and may transmit DMRS2 on those subcarriers.

Moreover, if P2<P_(CMAX,total), the UE may adjust the first ULtransmission power 402 to result in the first transmission power 702equal to {tilde over (P)}₁ (=min{P_(CMAX,c1), P_(CMAX,total)−P2,(1+γ)P1}) during T2, where γ≥is a maximum boosting factor for the powerof the first UL transmission 402. Upon completion of the second ULtransmission 406, the UE may re-adjust the first UL transmission 402 toresult in the first transmission power 702 power equal to P ₁(=min{P_(CMAX,c1),(1+γ)P1}) and complete the first UL transmission 402.In some embodiments, the UE may send an indication to cell c1 toindicate puncturing (e.g., a flag F3=1) that may occur if additionalsignals are transmitted, such as additional DMRS. Because the UE outputpower setting is changed from P1 to {tilde over (P)}₁ and then again toP ₁ during the first UL transmission 402, the UE may multiplex two setsof additional demodulation reference signal, DMRS2 and DMRS3, into thefirst UL transmission 402 to facilitate coherent decoding upon eachinstance of changing the total output power setting (e.g., immediatelyat the starting time of the second UL transmission 406—the second time712, and immediately after completion time of the second UL transmission406—the third time 714). In some embodiments, one incentive for powerboosting for the first UL transmission 402 and assigning a power levellarger than the originally configured power P1 is to increase thereliability of the first UL transmission 402 as much as possible byincreasing the transmission power and to minimize and/or compensate forany penalizing impact on the performance of the first UL transmission402 caused by puncturing the data of the first UL transmission 402 forinsertion of additional DMRS. The total power transmission 706 is equalto P1 between the first time 708 and the second time 710, the totalpower transmission 706 is equal to Min{P_(CMAX,c1)+P2, P_(CMAX,total),(1+γ)P1+P2} between the second time 710 and the third time 712, and thetotal power transmission 706 is equal to Min{P_(CMAX,c1), (1+γ)P1}between the third time 712 and the fourth time 714.

In various embodiments described herein, the flags F1, F2, and/or F3 mayinclude one or more bits and may represent a power offset termcorresponding any change in the first UL transmission 402 transmit powerduring an overlap between the first transmission period 404 and thesecond transmission period 408. In such embodiments, one of the statesof the flags F1, F2, and/or F3 may represent puncturing or notransmission.

The various embodiments described in FIGS. 5 through 7 may be applied toconfigurations in which slot-timing and/or symbol-timing of first andsecond serving cells are synchronous. In such configurations, a UEreceiver may detect the same DL slot-boundaries and/or symbol-boundariesfor the first and second serving cells for a given numerology and/orSCS. In some embodiments, if a symbol of one UL transmission having afirst symbol duration that partially or completely overlaps one or moresymbols of an other UL transmission having a second symbol duration, andif a transmission power of the symbol of the first symbol duration needsto be adjusted (e.g., to reduce power or for no transmission) toaccommodate the other UL transmission of the second symbol duration, theadjusted power may be applied for the entire symbol having the firstsymbol duration.

Moreover, the various embodiments described in FIGS. 5 through 7 may beapplied to configurations in which there is a partial overlap betweenfirst and second UL transmissions (e.g., if only part of the timeduration T2 for the second UL transmission 406 overlaps with the firstUL transmission 402). In certain embodiments, a UE may apply the variousembodiments described in FIGS. 5 through 7 with the exception thatoperations and/or procedures described for an overlapping time may beapplied only to a partial overlap duration, and the operations and/orprocedures described for the remaining symbols of the first ULtransmission 402 after the completion of the second UL transmission 406may not be needed if there is no remaining first UL transmission 402after the partial overlap duration.

Furthermore, in the various embodiments described in FIGS. 5 through 7,in order for a gNB to decode heterogeneous transmissions in view ofabrupt power changes, the gNB may estimate a RX power change (orestimate of TX power differences between UL1 and UL2 transmissions basedon an estimate from PHR), and then scale LLRs to account for powerchanges for the first UL transmission 402.

The various embodiments described in FIGS. 5 through 7 may differentlyimpact performance corresponding to the first UL transmission 402 andthe second UL transmission 406. Therefore, a gNB may determine one ofthe embodiments described in FIGS. 5 through 7 to use and may indicatethe determined embodiment to a UE based on configurations of twoconcurrent UL transmissions. The gNB may determine the embodiment to usebased on: a difference between an estimate by the gNB of power P1 forthe first UL transmission 402 and a maximum configured power P_(CMAX,c1)for serving cell c1; a difference between a maximum configured totaland/or aggregate power P_(CMAX,total) across two serving cells and themaximum configured power P_(CMAX,c1) for serving cell c1; a power P2 forthe second UL transmission 406; the time duration T2 for the second ULtransmission 406; a number of symbols left for the first UL transmission402 after completion of the second UL transmission 406; and/or acontents of symbols at a starting time and/or a completion time of thesecond UL transmission 406 (e.g., whether the symbols include UCI).

In one embodiment, a gNB may configure a UE to use one of theembodiments described in FIGS. 5 through 7 based on high-layer signaling(e.g., using a MAC control element, using RRC signaling, etc.). Inanother example, a UE may decide and indicate (e.g., dynamically,semi-dynamically, and/or semi-statically) to the gNB which method itwill select based on the configurations of the two UL transmissionsincluding the aspects above.

In certain embodiments, if P1 has a value close to P_(CMAX,c1) (e.g., adifference between P1 and P_(CMAX,c1) is smaller than a predeterminedthreshold), then a UE may use the embodiment described in relation toFIG. 5. In some embodiments, if symbols of the first UL transmission 402near a starting time and/or a completion time of the second ULtransmission 406 include UCI, then a UE may adopt the embodimentdescribed in relation to FIG. 5 to reduce abrupt power and/or phasechange that may necessitate puncturing UCI symbols for insertion ofadditional DMRS. In various embodiments, if a difference betweenP_(CMAX,c1) and P_(CMAX,total) is small (e.g., smaller than a firstthreshold), the time duration T2 for the second UL transmission 406 issmall (e.g., smaller than a second threshold) and/or few symbols areleft for the first UL transmission 402 after completion of the second ULtransmission 406 (e.g., smaller than a third threshold), then a UE mayuse the embodiment described in relation to FIG. 6 to reduce repetitivepuncturing of the first UL transmission 402. In certain embodiments, ifa difference between P_(CMAX,c1) and P_(CMAX,total) is large (e.g.,larger than a first threshold), P2 is large (e.g., larger than a secondthreshold), the time duration T2 for the second UL transmission 406 islarge (e.g., larger than a third threshold), and/or many symbols areleft for the first UL transmission 402 after completion of the second ULtransmission 406 (e.g., larger than a fourth threshold), then a UE mayuse the embodiment described in relation to FIG. 7 to provide powerboosting for the first UL transmission 402 and/or to reduce performanceloss resulting from high power and long overlap with the second ULtransmission. In a further example, the UE may cease/drop the first ULtransmission after the completion of the second transmission if fewsymbols are left (e.g., less than a certain threshold) or if thecorresponding allocated power in either second or third method orvariations thereof is small (e.g., smaller than another certainthreshold).

In some embodiments, the second UL transmission 406 having transmitpower P2 (e.g., also having a shorter transmission duration and/or ahigher priority than the first UL transmission 402) may occursemi-persistently within the first UL transmission 402. For example, thesecond UL transmission 406 may include short PUCCHs carrying HARQ-ACKfeedback for semi-persistently scheduled non-slot based PDSCHs,therefore, a UE may change the first UL transmission 402 power betweenMin{Max{0, P_(CMAX,c1)−P2}, P1} and Min{P_(CMAX,c1), P1+P2} depending onwhether the first UL transmission 402 overlaps the second ULtransmission 406 (e.g., Min{Max{0, P_(CMAX,c1)−P2}, P1} duringoverlapping portions and Min{P_(CMAX,c1), P1+P2} during non-overlappingportions).

In various embodiments, if a UE performs one or more heterogeneousuplink transmissions using multiple power amplifiers (e.g., forinter-band CA or possibly intra-band non-contiguous CA), a constant PApower setting for the entire transmission duration or changing the powersetting with insertion of additional DMRS may be determined per PA. Inan embodiment illustrated in FIG. 8, a UE may puncture the first ULtransmission 402 completely during T2, and may boost transmission powerto P1′ (≤P_(cmax,c1)) upon completion of the second UL transmission 406(and may multiplex an additional DMRS for new phase and/or channelestimation). In such an embodiment, power boosting for the remainingtransmission time of the first UL transmission 402 may compensate for apotential performance loss due to puncturing during T2. In an embodimentillustrated in FIG. 9, a UE may adjust a transmit power of the first ULtransmission 402 from P1 to Min{Max{0, P_(CMAX,c1)−P2}, P1}, wherein adifference between P1 and the new power level Min{Max{0,P_(CMAX,c1)−P2}, P1} may not be significant (e.g., less than aconfigured, predefined, and/or dynamically signaled threshold value),and maintain the adjusted transmit power until the end of the first ULtransmission 402. As may be appreciated, by maintaining the sameadjusted transmit power for the remaining transmission, the UE can relyon a single additional DMRS2 for coherent demodulation during and afterthe overlap time with the second UL transmission 406 and may avoidinserting a further additional DMRS (i.e., a total of at least two setsof additional DMRSs).

FIG. 8 is a schematic block diagram illustrating yet another embodimentof a timing diagram 800 of power settings. The timing diagram 800illustrates a first transmission power 802 for the first UL transmission402 described in FIG. 4, a second transmission power 804 for the secondUL transmission 406 described in FIG. 4, and a total transmission power806 that is a sum of the first transmission power 802 and the secondtransmission power 804. Furthermore, the timing diagram 800 illustratesa first time 808, a second time 810, a third time 812, and a fourth time814. The first time 808 corresponds to a starting time of the first ULtransmission 402, and the fourth time 814 corresponds to an ending timeof the first UL transmission 402, thus, the first transmission period404 of FIG. 4 equals the time between the first time 808 and the fourthtime 814. Moreover, the second time 810 corresponds to a starting timeof the second UL transmission 406, and the third time 812 corresponds toan ending time of the second UL transmission 406, thus, the secondtransmission period 408 of FIG. 4 equals the time between the secondtime 810 and the third time 812.

As illustrated, the UE may transmit, with power P1, the first N1 symbols(e.g., having a duration less than the first transmission period 404) ofthe first UL transmission 402 prior to and up to the start of the secondUL transmission 406. Thus, between the first time 808 and the secondtime 810, the first transmission power 802 equals P1. In one embodiment,a first DMRS is transmitted at or near the beginning of the first ULtransmission 402 (e.g., front-loaded near the beginning of the first N1symbols).

During the second transmission period 408, the UE may transmit thesecond UL transmission 406 with the power P2. Thus, between the secondtime 810 and the third time 812, the second transmission power 804equals P2. Because the second transmission period 408 starts at thesecond time 810 and ends at the third time 812, the second transmissionpower 804 equals zero between the first time 808 and the second time810, and between the third time 812 and the fourth time 814.

During the first transmission period 404 between the second time 810 andthe third time 812, the first transmission power 802 equals 0. Moreover,during the first transmission period 404 between the third time 812 andthe fourth time 814, the first transmission power 802 is ≤P_(cmax,c1).

The total power transmission 806 is equal to P1 between the first time808 and the second time 810, the total power transmission 806 is equalto P2 between the second time 810 and the third time 812, and the totalpower transmission 806 is ≤P_(cmax,c1) between the third time 812 andthe fourth time 814.

FIG. 9 is a schematic block diagram illustrating yet a furtherembodiment of a timing diagram 900 of power settings. The timing diagram900 illustrates a first transmission power 902 for the first ULtransmission 402 described in FIG. 4, a second transmission power 904for the second UL transmission 406 described in FIG. 4, and a totaltransmission power 906 that is a sum of the first transmission power 902and the second transmission power 904. Furthermore, the timing diagram900 illustrates a first time 908, a second time 910, a third time 912,and a fourth time 914. The first time 908 corresponds to a starting timeof the first UL transmission 402, and the fourth time 914 corresponds toan ending time of the first UL transmission 402, thus, the firsttransmission period 404 of FIG. 4 equals the time between the first time908 and the fourth time 914. Moreover, the second time 910 correspondsto a starting time of the second UL transmission 406, and the third time912 corresponds to an ending time of the second UL transmission 406,thus, the second transmission period 408 of FIG. 4 equals the timebetween the second time 910 and the third time 912.

As illustrated, the UE may transmit, with power P1, the first N1 symbols(e.g., having a duration less than the first transmission period 404) ofthe first UL transmission 402 prior to and up to the start of the secondUL transmission 406. Thus, between the first time 908 and the secondtime 910, the first transmission power 902 equals P1. In one embodiment,a first DMRS is transmitted at or near the beginning of the first ULtransmission 402 (e.g., front-loaded near the beginning of the first N1symbols).

During the second transmission period 408, the UE may transmit thesecond UL transmission 406 with the power P2. Thus, between the secondtime 910 and the third time 912, the second transmission power 904equals P2. Because the second transmission period 408 starts at thesecond time 910 and ends at the third time 912, the second transmissionpower 904 equals zero between the first time 908 and the second time910, and between the third time 912 and the fourth time 914.

During the first transmission period 404 between the second time 910 andthe fourth time 914, the first transmission power 902 equals Min{Max{0,P_(CMAX,c1)−P2}, P1}.

The total power transmission 906 is equal to P1 between the first time908 and the second time 910, and the total power transmission 906 isequal to Min{P_(CMAX,c1), P1+P2} between the second time 910 and thefourth time 914.

In one embodiment, a UE may maintain a collection of the followingpathloss estimates for the purpose of PUSCH, PUCCH, and/or SRS powercontrol in a multi-beam wireless network: (a) pathloss estimates for allor a subset of gNB beams corresponding to actually-transmitted SSblocks; (b) pathloss estimates for all or a subset of active gNB beamsfor PUSCH and/or SRS transmission (e.g., a gNB SS block and/or CSI-RSbeams configured for current monitoring—CSI acquisition—and/or potentialPUSCH scheduling); (c) pathloss estimates for all or a subset ofalternative and/or candidate gNB beams (e.g., beams used for beamswitching); (d) pathloss estimates for all or a subset of gNB beamscorresponding to and/or associated with configured SRS resources for anUL beam management procedure; (e) pathloss estimates for all or a subsetof active gNB beams for PUCCH transmission, if different from PUSCHbeams (e.g., for robust transmission of control information), includingbeams configured for a beam failure detection procedure; and/or (f)pathloss estimates for all or a subset of configured gNB beams formobility, RRM, RLM, and/or BFR procedures. As may be appreciated, theabove sets of pathloss estimates may not be mutually exclusive and/ormay have non-empty overlaps.

In certain embodiments, for a system with a beam reporting procedure anda beam management procedure, a number of pathloss estimates to maintainmay not exceed a number of transmitted SS blocks and a fraction,multiple, or offset of a number of reported beams. For example, if a UEreports up to 4 good and/or active beams to a gNB, then the UE maymaintain no more than 8 pathloss estimates (e.g., 8 is a multiple of 4)for 8 beams corresponding to some of the transmitted SS blocks, activeCSI-RS beams, and/or candidate beams.

In various embodiments, a gNB may categorize sets of pathloss estimatesbased on a channel and/or signal for which power control is considered.In one embodiment, a gNB and/or UE may configure pathloss options (a),(b), (c), and/or (f) described herein for PUSCH power control; options(a), (b), (c), (d), and/or (f) described herein for SRS power control;and/or options (a), (b), (c), (e), and/or (f) described herein for PUCCHpower control.

In some embodiments, if a CA-capable UE is configured with multiplebandwidth parts with different numerologies, the UE may be configuredwith different open-loop power control parameters (e.g., differenttarget SINR P0 and fractional pathloss compensation factor alpha and/orpathloss reference signal) and/or different closed-loop power controlloops.

In certain embodiments, a first time a UE is configured and/orreconfigured with a bandwidth part having a corresponding numerologydifferent from a numerology corresponding to bandwidth parts that the UEis configured with, a PHR may be triggered to inform a gNB of an updatedestimate of interference and/or pathloss of a channel associated withthe configured and/or reconfigured bandwidth part.

In various embodiments, if a UE is configured to operate with one cell(perhaps among other configured cells), the UE may be configured withthe following OL power control configuration (e.g., target SINR P0and/or fractional pathloss compensation factor alpha) for dynamicscheduling: at least 2 distinct OL configurations for eMBB and URLLCservices; at least 2 distinct OL configurations for the two uplinks of aSUL configuration; and/or up to N_max distinct OL configurations fordifferent PUSCH beams, where N_max corresponds to a maximum number ofgood and/or active beams the UE reports in a beam management procedure.It should be noted that the above examples do not consider the impact ofslot sets, or the impact of slot sets are considered to be capturedalong with the OL-PC configuration allocation for beams.

In certain embodiments, a separate OL-PC configuration for PRACHtransmission may be used. Furthermore, in some embodiments, a separateOL-PC configuration for grant-free transmission may be used.

In various embodiments, a UE may have up to 4 active beams. Accordingly,the UE may have at least 14+1+1=16 different OL-PC configurations.

In one embodiment, if a UE in a multi-beam wireless network isconfigured with multiple closed loops for PUSCH power control (e.g., 2closed loops), a selection of a closed-loop configuration (e.g., a firstclosed loop, a second closed loop) may depend on an indication from agNB beam from a set of active gNB beams for PUSCH transmission to the UE(and perhaps the supplementary uplink (SUL) and/or slot-sets), but maynot depend on other PUSCH transmission features and/or attributes suchas grant type, service type, traffic type, and so forth. In such anembodiment, all PUSCH transmissions operating with the same gNB beam maybe configured with the same closed loop power control regardless of agrant type, traffic type, service type, and/or other PUSCH transmissionfeatures and/or attributes.

In certain embodiments, if a UE operates in a multi-beam wirelessnetwork, regardless of whether a PUCSCH transmission is configured witha single or multiple (e.g., 2) closed loops for power control, a stepsize 6 PUSCH for TPC command and/or an application-time K_PUSCH maydepend on a grant type, a service type, a traffic type, and/or otherPUSCH transmission features and/or attributes. For example, URLLC (incomparison with eMBB) or grant-free transmission (in comparison withdynamic-grant-based transmission) may have a larger step size 6 PUSCHand/or a shorter application time K_PUSCH for faster convergence ofclosed-loop power control.

In various embodiments, if a new gNB beam is added to a set of activegNB beams for a UE, and that gNB beam has similar spatial characteristicand/or QCL assumptions with an existing active gNB beam for the UE, thena current accumulation status of a closed-loop power control for theexisting active gNB beam may be applied to the newly added beam. In suchan embodiment, the gNB beam addition may not count as an RRCreconfiguration (e.g., reconfiguration of TCI and/or other power controlrelated RRC parameters) and/or may not cause any reset of a closed-looppower control parameter.

In some embodiments, if a new gNB beam is added to a set of active gNBbeams for a UE, and that gNB beam has significantly different spatialcharacteristic and/or QCL assumptions with all existing active gNB beamsfor the UE, then the accumulation of only the closed-loop power controllinked to the new gNB beam (and all other gNB beams sharing the sameclosed-loop power control) may be reset, but no other closed-loops mayreset upon this beam configuration and/or reconfiguration.

In one embodiment, if some spatial relations in a TCI get updated and/orreconfigured, for all PUSCH, SRS, and/or PUCCH transmissions thatcorrespond to the TCI update and/or reconfiguration, the accumulationstatus of a corresponding closed-loop power control process after theTCI update may reset or may inherit a current and/or last accumulationstatus that existed before the TCI update and/or reconfiguration. Insuch an embodiment, a decision to reset the accumulation may depend on asimilarity and/or difference of the spatial relations before and/orafter the TCI update. Moreover, in such an embodiment, for any PUSCH,SRS, and/or PUCCH transmissions that do not correspond to or associatewith that TCI update and/or reconfiguration, the accumulation status ofa corresponding closed-loop power control process may not reset afterthe TCI update and/or reconfiguration (e.g., the correspondingclosed-loop power control process may carry over a current status and/orlast status of a CL-PC process before the TCI update and/orreconfiguration).

In certain embodiments, if a first group of spatially similar gNB beams(e.g., those corresponding to one panel of a TRP) have significantlydifferent spatial characteristic and/or QCL assumptions than a secondgroup of gNB beam (e.g., those corresponding to a second panel of aTRP), a closed-loop power control configuration for a UE may choose onethe following two configurations: either each of the first and secondgroups of gNB beams may correspond to different closed loops for powercontrol; or if the UE attempts to switch from communication with a beamfrom the first group to communication with a beam in the second beamgroup, a corresponding closed-loop configuration may reset itsaccumulation

In various embodiments, if a multi-panel UE operates with a gNB beamusing a UE beam to a UE panel, and the UE is configured with a positiveTPC command that may cause the UE to exceed a maximum configured outputpower for the UE panel (e.g., P_(CMAX,c,b)) or the UE is operating in apower-limited mode, the UE may initiate an UE TX beam sweeping (e.g., aU3 UL beam management procedure) to determine whether any other UE beamsfrom any other UE panel exists that can operate with the same gNB beambut facilitate a larger panel-P_(CMAX,c,b). In such embodiments, if theUE finds any such UE TX beams, the UE may autonomously perform a UE TXbeam switching that is transparent to the gNB.

In some embodiments, if a UE is configured with multiple power controlparameter sets for PUSCH corresponding to a set of active gNB beams forpotential PUSCH transmission, a set of service types and/or traffictypes (e.g., eMBB and/or URLLC), a set of grant types (e.g.,grant-based, grant-free, and/or RAR), and/or any other PUSCH attributes,and if the UE is configured with several SRS resources for UL and/or DLCSI acquisition of active gNB beams for potential PUSCH transmission (ormultiple SRS resource sets each consisting of one or more of those gNBbeams), a configuration of power control parameter sets for the SRSresources may be tied to a configuration of power control parameter setsfor the active PUSCH beam, but may not be tied to different servicetypes, grant types, and so forth. For example, a configuration of apower control parameter set for each SRS resource aimed at UL and/or DLCSI acquisition of an active gNB beam for PUSCH transmission may be tiedto (e.g., follow, use the same values, use same values plus a configuredoffset, and so forth) a configuration of power control parameter setsfor a corresponding active gNB PUSCH beam and: (i) a fixed default setof PUSCH transmission features and/or attributes such as a service type,a grant type, and so forth; or (ii) a semi-statically varying set ofPUSCH transmission features and/or attributes such as a service type, agrant type, and so forth, based on a previous UE scheduling history(e.g., based on mostly used UE PUSCH transmission features and/orattributes in a time interval). In certain embodiments, if a high-layerpower control configuration for SRS resources aimed at UL and/or DL CSIacquisition of active gNB PUSCH beams is tied to a high-layer powercontrol configuration for those gNB PUSCH beam, and if a UE is scheduledwith transmission of a certain SRS resource that is aimed at UL and/orDL CSI acquisition of an active gNB PUSCH beam (e.g., based on alow-overhead mechanism for activation and/or triggering of SRS resourcesby indicating an SRS resource set that includes all SRS resources aimedat UL and/or DL CSI acquisition), the SRS resource indicator SRI (or anindicator for the SRS resource set aimed at UL and/or DL CSIacquisition) may be indicated to the UE that may signal to the UE whichSRS and/or PUSCH power control configuration to follow.

In one embodiment, if a UE capability report includes an UL and/or DLnon-correspondence feature (e.g., the UE reports that it may not supportbeam correspondence due to one or some of the following reasons: the UEsometimes and/or always uses different panels for TX than RX; the UE haspoor calibration such as because there is a large phase offset betweenthe RX beams and the TX beams; the UE has restrictions on the usage ofthe TX beams, for example, all beams are possible for RX, but the UE canuse only certain beams for TX due to EIRP-like limitations; the TX andRX beams of the UE have different beam widths such as a narrower beamfor RX, but wider beams for TX; the TX and RX phasing network of that UEhave different granularities such as that RX uses finer phase shifts,but TX uses coarser phase shifts; and/or the UE beamforming capabilitiesare different for TX and RX such as only a limited number of beams (orbeam patterns) may be used for TX, but all of those beams (and beampatterns) as well as their linear combinations may be used for RX), thenthe UE may report to the gNB an average UL and/or DL mismatch offset foreach gNB beam. The average UL and/or DL mismatch may be a UE estimatedaverage power offset caused by any and/or all of the abovementionednon-correspondence features existing in the UE calculated for each gNBbeam if operating with a best UE beam as determined based on an UL beammanagement procedure. For example, the average UL and/or DL mismatchoffset may be based on a statistical analysis to bound performance ofelectronic, PA, RF, and/or antenna components or based on an empiricalaverage of power variation measurements in UE electronic, PA, RF, and/orantenna components over a time interval. In some embodiments, a gNB maytake gNB beam specific average UL and/or DL mismatch offset into accountif configuring a power control parameter sets for a UE. As may beappreciated, incorporating the average UL and/or DL mismatch offset mayfacilitates the gNB configuring a single gNB beam as a DL referencesignal for pathloss estimation for beam non-correspondence (e.g., asopposed to configuring multiple gNB beam as DL-RS for pathlossestimation through a uniform and/or weighted average), and any remainingerror and discrepancy may be small enough to be captured by a gNB TPCcommand with fast convergence in a timely manner.

In certain embodiments, if multiple UEs are configured with the same setof active gNB beams for PUSCH transmission, or if multiple UEs may sharea subset of gNB beams among configured gNB beams for their PUSCHtransmission, the gNB may group that set and/or subset of gNB beams, andmay attempt UL and/or DL CSI acquisition for that set and/or subset ofgNB beams jointly for the multiple UEs by jointly triggering and/oractivating SRS resources corresponding to that set and/or subset of gNBPUSCH beams (e.g., based on a low-overhead mechanism for activationand/or triggering those SRS resources such as by configuring andindicating an SRS resource set that includes all SRS resources relatingto UL and/or DL CSI acquisition of that set and/or subset of gNB PUSCHbeams). In such embodiments, the gNB may configure the multiple UEs witha group-common TPC command as part of group-DCI using TPC-SRS-RNTI tofacilitate a joint and/or low-overhead mechanism to signal power controladjustments for the SRS resources.

In various embodiments, if an SRS resource set and/or group isassociated with a set of gNB beams in an UL beam management procedure(e.g., for beam determination, switching, sweeping, and/or refinement),and if the SRS resource set and/or group is configured for multiple UEs(e.g., for lower overhead operation in any of the procedures: beammanagement, triggering, activation, and/or power control), the gNB mayconfigure the multiple UEs with a group-common TPC command as part ofgroup-DCI using TPC-SRS-RNTI.

In some embodiments, if SRS transmission is not tied to any PUSCHtransmissions (e.g., SRS transmission is not aimed at UL and/or DL CSIacquisition of any active gNB beam for potential PUSCH transmission), agNB may configure a UE with one independent closed-loop power control orno closed-loop power control. In one example, if SRS transmission isconfigured for SRS antenna switching and/or SRS carrier switching, withno correspondence to PUSCH and/or PUCCH transmission, then a separateindependent closed-loop may be configured for the SRS transmission. Inanother example, if an SRS resource set and/or group contains multipleperiodic SRS resources (of the same periodicity) aimed at UL beammanagement, the gNB may configure an independent closed-loop power forthe SRS resource set and/or group. In yet another example, if a firstSRS resource set and/or group includes multiple aperiodic SRS resourcesfor UL beam management, and if the aperiodic SRS resources areassociated with the same gNB beams (or a subset of those gNB beam ofsize larger than a certain threshold) that a second SRS resource sethaving periodic SRS resources is also associated with, then aclosed-loop power control of the second SRS resource set and/or groupmay be configured for the first SRS resource set and/or group, and anyaccumulated status may carry over. In a further example, if an SRSresource set and/or group includes multiple aperiodic SRS resources thatcorrespond to a set of gNB beams that are not associated with any otherSRS resource sets and/or groups having periodic SRS resources (e.g., ifaperiodic SRS resources correspond to a new set of gNb beams as newcandidates that are not previously configured before in the UL beammanagement procedure), then the gNB may configure no closed loop powercontrol for that SRS resource set (e.g., to rely only on open loop powercontrol).
